Memcached::flush

(PECL memcached >= 0.1.0)

Memcached::flush — Invalidate all items in the cache

Descrizione

publicboolMemcached::flush
([ int$delay = 0
] )

Memcached::flush() invalidates all existing cache items
immediately (by default) or after the delay
specified. After invalidation none of the items will be returned in
response to a retrieval command (unless it's stored again under the same
key after Memcached::flush() has invalidated the items).
The flush does not actually free all the memory taken up by the existing
items; that will happen gradually as new items are stored.
